In order that the flange of the device does not leak oil, the requirements and precautions of the device are as follows:
The main results are as follows:
(1) The flange should have sufficient strength and should not be deformed when fastening. The flange cover shall be smooth and clean, and oil and rust shall be removed carefully during installation.
(2) The gasket should have good oil resistance, aging resistance, and has considerable elasticity and mechanical strength. The equipment should select different gasket sections and sizes according to the shape of the connection and place them correctly.
(3) the fastening force of the stainless steel flange should be evenly divided, and the contraction of the rubber pad should be controlled in the left 1/3. Stainless steel flanges are stopped in practice in a normal manner and in principle to the highest quality and value types in application, and are used and installed in accordance with normal operating specifications without quality and performance problems. Stainless steel flange is not a simple mechanical part in general sense, but a mechanical product carrier with rich technical connotation.
First, large stainless steel flanges should have sufficient strength and should not deform during fastening. Flange sealing surface should be smooth and clean. Oil and rust should be removed carefully during installation. Large stainless steel flange joint is easy to use and can bear greater pressure. Flanged connections are commonly used in industrial pipelines. Small diameter and low pressure pipe series. If in boiler room or consumption place, there are pipes and flange connection equipment everywhere. The device should choose different sections and sizes of gaskets according to the shape of the connection, and place them correctly. The fastening force of stainless steel flange should be evenly distributed, and the contraction of rubber pad should be controlled at 1/3 on the left side.
